Code-reuse attacks by corrupting memory address pointers have been a major threat of software for many years. There have been numerous defenses proposed for countering this threat, but majority of them impose strict restrictions on software deployment such as requiring recompilation with a custom compiler, or causing integrity problems due to program… (More)

Silva et al. proposed a universal secure network coding scheme based on MRD codes, which can be applied to any underlying network code. This paper considers a stronger eavesdropping model where the eavesdroppers possess the ability to re-select the tapping links during the transmission. We give a proof for the impossibility of attaining universal security… (More)

This paper reports a large-scale study that aims to understand how mobile application (app) vulnerabilities are associated with software libraries. We analyze both free and paid apps. Studying paid apps was quite meaningful because it helped us understand how differences in app devel-opment/maintenance affect the vulnerabilities associated with libraries.… (More)
